Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling circuit arrangements in motor vehicles face challenges in reducing installation space and the number of parts, which affects overall vehicle design efficiency and acoustic emissions.
Innovation Solution
The pump housing is partially integrated into the tank or distributor device, forming a unified structure that eliminates the need for additional housing components, and incorporates features like annular grooves and recesses/projections for improved sealing and support, enhancing operational efficiency and acoustic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete pump is connected to the distributor device or tank as in conventional arrangements, then the pump can function independently, but the number of parts and construction volume increase
Solution Approach 1:
The pump housing is merged with the distributor device by integrating the first part of the pump housing directly into the distributor device structure. This eliminates the need for a separate complete pump housing component, reducing the number of parts while maintaining the pump's functional integrity through the combined structure.
2Reliability
If a complete pump is connected to the distributor device or tank, then the pump can operate independently, but the installation space increases
Solution Approach 1:
The pump housing is merged with the tank by integrating the first part of the pump housing into the tank structure. This consolidation eliminates the need for a separate complete pump housing, thereby reducing the overall installation space while preserving the pump's operational independence through the integrated design.
3Device complexity
If the first part of the pump housing is formed in the tank or distributor device, then the number of parts is reduced, but additional sealing measures are required
Solution Approach 1:
The sealing function is extracted as a distinct feature and implemented through specific structural elements (collar and annular groove) within the integrated housing. This separation of sealing as a distinct functional element simplifies the overall manufacturing process despite the integration, as the sealing mechanism can be independently designed and implemented.
Solution Approach 2:
The collar and annular groove act as intermediary sealing elements between the integrated housing parts. These intermediary structures provide the necessary sealing function without requiring complex sealing measures, facilitating easier manufacture of the integrated pump housing.
4Ease of manufacture
If the impeller collar engages in the inlet instead of an annular groove, then the assembly is simpler, but unwanted liquid flow increases and efficiency decreases
Solution Approach 1:
The sealing function is extracted from the simple collar-inlet engagement and implemented through a dedicated annular groove structure. This separation allows the collar to maintain its simple assembly function while the annular groove provides the necessary sealing to prevent unwanted liquid flow, thereby maintaining pump efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This integration reduces the number of parts and installation space while improving sealing, reducing unwanted liquid flow, and enhancing the acoustic properties of the pump, leading to smoother operation and better efficiency.
Implementation Method 1
A seal can be created between an inlet and the pump chamber by the meshing of the collar of the impeller and the annular groove of the first part of the housing or of the collar of the first part of the housing and the annular groove of the impeller. The seal can be a labyrinth seal or be similar to a labyrinth seal.
Implementation Method 2
a pump according to the invention can have a second bearing for the rotating parts of the pump, which bearing assists in supporting the rotating parts of the pump
